C>S 0x58 SID_AUTH_ACCOUNTUPGRADEPROOF
Message Id:0x58
Message Name:SID_AUTH_ACCOUNTUPGRADEPROOF
Direction:Client to Server
Flags: Deprecated
Used By:Warcraft III Reign of Chaos, Warcraft III The Frozen Throne
Format:

(UINT32) Client Token
(UINT32) [5] Old Password Hash
(UINT8) [32] New Password Salt
(UINT8) [32] New Password Verifier

Remarks

Converts the stored XSHA-1 password hash to a new NLS/SRP password. However, this message is no longer responded to, and upgrading accounts is therefore impossible.

Note: If you have an account in need of upgrading (created with C>S 0x3D SID_CREATEACCOUNT2), you can let the account expire and recreate it with C>S 0x52 SID_AUTH_ACCOUNTCREATE.

*Old Password Hash:

Broken SHA-1 Double password hash as seen in C>S 0x3A SID_LOGONRESPONSE2.

New Password Salt & Verifier:

Salt and Verifier values as seen in C>S 0x52 SID_AUTH_ACCOUNTCREATE.

Old Password is the account's current password. The New Password can be the same as the Old Password, but it can be used to change the password as well.
